Does a model using generalized pulse wave velocity accurately estimate systolic blood pressure during short effort bicycle tests?
A cuffless blood pressure estimation model incorporating pre-ejection period achieves acceptable accuracy during short-term physical stress tests.
May support cuffless SBP monitoring during exercise; leaves open clinical adoption pending prospective validation.
This paper investigates the specific contributions of the pre-ejection period (PEP) and pulse transit time (PTT) for blood pressure estimation based on the pulse wave methodology. We show that in short-term physical stress tests, PEP dominates PTT variations raising the question of a suitable blood pressure calibration. A model using a generalized pulse wave velocity achieves acceptable accuracy for systolic blood pressure estimation, given our experimental conditions.

Muehlsteff et al. (2006) studied this question. Cuffless estimation of systolic blood pressure using pre-ejection period (PEP) and pulse transit time (PTT) was evaluated on Accuracy of systolic blood pressure estimation. A model using generalized pulse wave velocity, where the pre-ejection period dominates pulse transit time variations, achieves acceptable accuracy for cuffless systolic blood pressure estimation.
